Graph f(x)=|x|+1 on the interval [-3,3]

The left graph is a sample graph (I believe?)

Which three lengths could be the lengths of the sides of a triangle? 21 cm, 7 cm, 7 cm 9 cm, 15 cm, 22 cm 13 cm, 5 cm, 18 cm 8 cm, 23 cm, 11 cm

Icould really use some with this question.

What is the graph of the absolute value equation ? y=|x|-5
